IMPROVEMENT IN OILING MILLSTONE-SPINDLES.

Specification forming part of Letters Patent No. 138,074, dated April22, 1873; application filed March 8, 1873.

To all whom it may concern:

Be it known that I, JOHN J. GHUBB, of Decatur, in the county of Adamsand State of Indiana, have invented a new and useful Improvement inOiling Millstone-Spindle, of which the following is a specification:

Figure l is a detail vertical section of the curb or hoop and lower orstationary stone of a run of burrs with which my improvement has beenconnected, taken through the line as as, Fig. 2. Fig. 2 is a top view ofthe same, part of the hoop or curb being broken away. Fig. 3 is a detailsection taken through the line y 3 Fig. 1. Fig. 4 is a detail view ofthe wire for cleaning out the oilin g-tube.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved device for oilingmillstone-spindles, by the use of which the spindle may be kept properlyoiled, and which shall be convenient in use. The invention consists inthe tube embedded in a channel in the leading furrow of the stationarystone, and extending from the heel or skirt to the bosom of said stone;in the tube provided with an oil-cup, in combination with the hoop orcurb, the tube embedded in the stationary stone, and the spindle, ashereinafter more fully described.

A represents the lower or stationary stone of a run of burrs. Brepresents the hoop or curb which incases the upper stone or runner, andG is the spindle. In the leading furrow of the stone A is formed achannel lead ing from the heel or skirt to the bosom. This channel mustbe sufficiently deep to receive a tube, D, and allow it to be coveredwith some suitable cement. E is a tube, which passes through the hoop orcurb B, and through the tube D, and is made of such a length as to reachto or nearly to the spindle G. The part of the tube E that passesthrough the hoop or curb B is made a little larger and stronger than therest of said tube, to guard against its being injured by the tremble ormovement of the said hoop or curb B. Upon the outer part of the tube Eis formed a cup, F, to receive the oil or other lubricating material,and which is provided with a cap or cover. The outer end of the tube Eis provided with a cap, cork, or other stopper, to enable a wire, G, tobe inserted to clear out the tube E, to avoid the too frequent removalof the tube E, and to be sure that it has not been injured by thepassage of a nail or other hard substance through the burrs.

Having thus described my invention,I claim as new and desire to secureby Letters Patentl. The tube D, embedded in a channel in the leadingfurrow of the stationary stone A, and extending from the heel or skirtto the bosom of said stone, substantially as herein shown and described.

2. The tube E, provided with an oil-cup, F, in combination with the hoopor curb B, the tube D embedded in the stationary stone, A, and thespindle G, substantially as herein shown and described.

JOHN J. GHUBB.
